Michael Joseph Childers, 27, a former student, was arrested in Broken Arrow about 8 p.m., OU police Lt. Bruce Chan said. Information on the complaints on which he was arrested were not available Friday night. Chan said the police department received a call from Kaufman Hall shortly before 4 p.m. that a man with a gun had just left the building. Officers began a search of the area. The gun was not discharged, and the man left the building a short time later, a statement released by OU President David Boren said.
 “According to our best information, this never constituted a threat to members of the general university community, but was considered a domestic dispute between two individuals,” Boren wrote. The emergency protocol worked as it was designed to, said Catherine Bishop, the university’s vice president of communication. In 2007, Childers was charged with a misdemeanor. Childers used his University of Oklahoma e-mail account to gain access to Mano Yasuda’s OU e-mail account, made purchases and had them charged to her, according to court documents. Childers entered a no contest plea and received a one-year deferred sentence, records show. Broken Arrow police Maj. Carole Newell said Childers lives in Broken Arrow and was arrested on an attempted kidnapping warrant.
